However, the device came in a bulk pack, much like what I've come to think is the OEM method of shipping ...
When I've bought Arduinos from Adafruit, they always come in the "official" box which has colour printing on it. So it appears that Arduinos, even when shipped in bulk to resellers, are not shipped in plain boxes. After all, it's not like a hard disk, where an OEM would take it out of the box, throw the box away, and put the hard drive into a computer. The Arduino is the end product.
